  • XYDiagram2D.DiagramToPoint(String, TimeSpan) Method

    Converts a point’s diagram coordinates into screen coordinates.

    Namespace: DevExpress.XtraCharts

    Assembly: DevExpress.XtraCharts.v25.1.dll

    NuGet Package: DevExpress.Charts

    #Declaration

    public ControlCoordinates DiagramToPoint(
        string argument,
        TimeSpan value
    )

    #Parameters

    Name Type Description
    argument String

    The point’s argument.

    value TimeSpan

    The point’s value.

    #Returns

    Type Description
    ControlCoordinates

    A ControlCoordinates object that contains information about the point’s screen coordinates, and its associated pane.

    #Remarks

    Use the DiagramToPoint method, to convert a point’s diagram coordinates (measured in axis units) to the screen coordinates (from the top-left window corner in pixels). For example, calling this method in the ChartControl.CustomPaint event handler allows you to obtain screen coordinates of series points, and draw custom graphics onto your chart across them.

    Note

    For the opposite conversion (of screen coordinates to diagram coordinates), use the XYDiagram2D.PointToDiagram method.

    With the Radar and Polar diagram types, use the similar RadarDiagram.PointToDiagram and RadarDiagram.DiagramToPoint methods.
